Add in pretzels and stir to combine. Stir in sesame sticks, soy nuts and peas (order is important for baking).

Pour mixture onto a rimmed baking sheet. Bake in the center of the oven for about one hour, stirring about every 15 minutes, until walnuts are a deep golden colour and mixture is toasted. Let cool.
